All of our master key systems are unique to each customer and expansion is never a problem. Every customer has a unique system number without any duplication. We can build hundreds of unique locks all under one master key if required.

Tenants keys can open communal front/back doors and their own room, cleaner keys just open main communal areas, sub master keys open everything at that address etc etc. Your grand master key will always open everything!

All of our systems involve our secure & unique patented key system which means your keys can not be copied by anyone without your written permission.
